Just incase anyone gets the same prob as me...i just spent the last day trying to re-flash my xecuter 2.2 lite in my 1.2 xbox and all along was confused as to why it wasnt working!! The xbox worked fine, the mod chip (bar a bad flash of an incorrect BIOS - namely the evox 2.5 which isn't even remotely close to what i should have been using) worked and the programmer flashed the chip fine (or so it seemed)...however, after reinstalling the mod chip, i still found the flashing red green light problem...

The answer?

Go into the BIOS of your PC (usually accessed by pressing DEL or ESC or an F key on startup, and go to the menu that adjusts ports...then, simply change your parallel port to EPP mode. It worked first go after so much headache it's unreal!!! The xecuter 4997 1 meg file went in lovely and now I'm happy TIP to find it - search GOOGLE for 'executer 4977 download' and it's the top result.
